FTP自动上传脚本，并发送邮件提醒

在内外网隔离的环境下，内网需要提交客户端到外网，必须通过运维。
脚本实现功能：当内网指定目录有提交新文件时、自动上传、不重复上传、上传完毕，生成下载地址发送给需要收到通知的人

#!/bin/bash
# 存放新客户端目录
ftpdir=/home/clinet  
# 存放已上传客户端目录
ftpbak=/home/clinet/complete  
# 接收邮件提醒的邮箱地址,多的话用空格隔开
mails=(admin@imdst.com)  
for client in $ftpdir/*  
do  
        if [ ! -f $client ]
                then 
                        echo "client no found"
                        exit
        fi

        echo "begin put $client ,please wait ......"

        for a in $ftpbak/*
        do
                if [ $a == $client ];then
                                for mail in ${mails[@]} ; do

                                done
                                exit
                fi
